P - 1

Unplug

Obligatory

If any abnormal smell or sound, or overheating or smoke should be detected, turn OFF the instrument immediately and then unplug it. If it should continue in use, a fire may break out on the instrument resulting in its malfunctioning. Contact your Kowa dealer where you purchased it or your nearest repair shop for inspection.

Before replacing the electric flash light tube, make sure that the instrument is turned OFF and the plug has been pulled out of the wall outlet. Allow at least five minutes to cool it off before replacement. Otherwise, you may burn your fingers on the hot tube and/or get an electrical shock.

When replacing the fuse, make sure the instrument is turned OFF and unplugged out of the socket. If the fuse holder cover is removed with the instrument unplugged, you may get an electrical shock.

Make sure that the instrument or AC adapter is properly plugged into the socket. If not, there may occur a fire or you may get an electrical shock.

Use an accessory or designated fuse. Otherwise, the instrument may malfunction or a fire may break out.

Make sure that the instrument is properly grounded to protect the body. Put the plug in the three-core socket with ground wire. Otherwise, you may get an electrical shock.

Prohibitory

Disassembly

prohibited

Prohibitory

Install in a location away from, for instance, a cup containing liquid. If liquid should be spilled into the instrument, you may get an electrical shock. If so, turn OFF the instrument and then unplug it from the socket. Contact your Kowa dealer where you purchased it or your nearest repair shop for inspection.

Do not disassemble, modify or repair the instrument yourself. Otherwise, there may occur a fire and resultant instrument malfunctioning or your may get an electrical shock and a bodily injury. Contact your Kowa dealer where you purchased the instrument for repair. The product assembled by yourself will not get warranty or any other service.

The socket or plug board must not be loaded in excess of its rated capacity. If the main power cable should share an outlet with many other devices, there may occur a fire or you may get an electrical shock.

If any metallic object in air vent slots should be inserted, there may occur a fire and resultant instrument malfunctioning .or you may get an electrical shock.

Do not damage the power cable. If it should be damaged, there may result a fire or you may get an electrical shock. Therefore, strictly observe the following:

-Neither modify nor damage the power cable.

-Do not place any heavy object on the power cable or pull it with a sudden jerk.

-Neither bring the power cable close to any hot surface of heater nor directly heat it.

P - 2

Be sure to use an accessory or designated lamp. Otherwise, there may occur a fire or resultant instrument malfunctioning.

Obligatory

Prohibitory

For unplugging from the socket, pull the power cable with its plug being held by your hand. Otherwise, there may occur a fire or you may get an electrical shock.

Do not plug into or unplug out of the socket with your wet hand to avoid an electrical shock.

Do not place the instrument in an unstable location, for instance, on a shaky base or a tilting surface. Otherwise, if it should drop off or fall over, you may get injured.

Do not replace the electric flash light tube and the illumination light immediately after their service. Otherwise, you may burn your fingers on the hot surface of the tube or lamp. Allow 30 minutes or so to cool it off before replacement.

Do not increase the amount of illumination light more than is required. Otherwise, the eye may get a pain or injured.

For illumination and photography, do not select any higher exposure than it is required Otherwise, the examined eye may suffer a pain or disorder.

Be careful about the gap between the light projecting prism and the patient's face. Otherwise, when bringing the fundus camera unit closer to the patient, the prism may touch and hurt his or her face (the eye, nose and so on).

Prohibitory

Unplug

Prohibitory

Do not use the instrument in a location having too much moisture, dust, soot or steam. In such a location, there may occur a fire or you may get an electrical shcok.

Do not touch the instrument with your wet hand to avoid an electrical shock.

If there is no need to use it for a long period of time, store the instrument with its power cable disconnected from the socket. Otherwise, there may occur a fire.

Use or carry the instrument with its being firmly held by your hand. Otherwise, if it should drop off, you may get injured.

OPERATING PRECAUTIONS

●Carefully handle the instrument so that a strong shock will not be exerted on it. After it sustained a strong shock or damage resulting from dropping off or any other mishandling, do not turn on the instrument.

●The instrument should be placed or stored in a place free from dust, high temperatures, high humidity and direct sunlight. The environmental conditions described below should be observed strictly.

in operation In storage and transportation

Environmental temperature 10 to 40°c -15 to +55°c

Relative humidity 30 to 75% 10 to +95%

●When not in use, make sure the camera unit is protected by its objective lens cap or cover.

●If it has not been in service for a long period of time, make sure the instrument has no abnormality prior to use.

●Be careful not to let any condensation form on this instrument when in use, storage, or transportation.

Precautions in operating electric system

●Be careful about where the camera is placed to keep its power plug from being disconnected during fundus photography.

●If the plug should accidentally come off, be sure to turn OFF the power switch before putting it again into the socket.

●If you put the plug back into the socket with the power switch ON and as a result any abnormality should occur on the

circuit inside of the power supply unit, be sure to turn OFF the power switch and then wait for a while before turning it ON again.

●The input voltage should be maintained within ±10% of the rated voltage.

●Do not turn the power switch ON and OFF in succession. Allow an interval of at least 5 seconds between switch

operations. Be sure to turn OFF the power switch before plugging and unplugging.

●The power line from the wall outlet should be exclusively used for the fundus camera.

Other precautions

●The manufacturer is not liable for malfunctions or injuries resulting from maintenance or repairs performed by a person other than a designated repair shop.

●The manufacturer is not liable for malfunctions or injuries resulting from modification, maintenance or repairs using parts other than designated repair parts.

●Because the camera is composed of precision parts, it needs a special set of tools for adjustment. Do not attempt to disassemble or adjust them by yourself.
